To all whom it may concern."

Be it known that 1, Henry Pnzzn'i'rr, a

- subject of theKing of Italy. but having de- -claredmy intention of becoming a cititen of the United States, and residing at Philadelphia, in the county of Philadelphla and State of Pennsylvania, United States of America, have'invented certain new and useful Improvements in Wagons, of which the following is aspecificatio'n.

-Objects of the present. invention are to provide a dump wagon or cart in which the center of gravity of the load shall be in front 6. the-rear axle so that the wagon,

more particularly the front wheels, will remain firmly on tho ground and will not tend. to rise or skid; to' provide for limiting the range of dumping motion of the body so that the end thereof will strike the ground in such a way that none of the parts areunduly strained or jarred; to provide simple and eflicient means whereby when the wagon is dumped the tail-board assumes such position that the center of gravity is so shifted that'the. body automatically returns'to nor' :mal position; to provide mechanismoper' ated by asinglehandle' and which by a -thebody and then single movement of the handle first releases ives it an initial dumping movement; and to provide-pivotal conncctions and their accessories by which the center "of gravity is shifted from in front carts and wagons, and their application to the latter has been selected for the sake of description and has been illustrated in the accompanying drawings, in -which- Figure 1, is a. side view, partly in section of a wagon embodying features of the invention and showingthe body in normal position'.' Fig. 2 is a similar view showing the bodyin dumping position and aboutjto In the drawings 1 and 2, are siderails and they may be the reaches of thewagon, as shown or "they may he shaftsor the slde bars of the frame or chassis of a motor truck. They are shownto consist of angle-irons.

is an axle secured tothe side rails.

4, is an inclined stop in rear' of the axle.

5,15 a support in front of the axle and 6, 1s a segment between. the stop and support;

7, 1s a pivot bracket having a pivot concentric with the segment and in front of the axle and below the rail.

All of the parts last described are carried I by'the rail and are present in duplicate, one set for each rail. These parts may be variously construct'ed and one way of constructing them is clearly shown in the drawings.

8, is a fittinghaving arms pivoted to the brackets 7 and arranged to cooperate with the support 4 and segment 6. As shown the fitting 8 has-a pair of arms-9 which straddle the rail and'are pivotally connected oneach side of the bracket 7. The fitting 8 is also pivotally supported.

Evidently the center of gravity, wnen the body is in normal position, is in front of the axle 3 (Fig. 1)-, whereas when the body is in dumped posit-ion, as shown'in Fig. 2, the center of gravity of the body, without regard to the tail-board 12, is in rear ofv the.

axleand the movement of the body is limited by the stops as shown.

13, is an arm pivoted intermediate of its ends to the body and 1 1 is an arm pivoted intermediate of its ends to the rails; the adjacent ends of these arms are connected by av link 15 and the tail-board 12 is attached to the ends of;the arms 13. Links 16 connect the ends of the arms 14 with the ,body.

The effect of these connections is that after the load is dumped tne weight of the tailboard operating through. the connections may be availed of for automatically returning the body to its normal position.

17, is a latch whichnormally engages a projection 18 on the body and locks it against dumping. The latch 17 is shown as Patented Jan. 13, 1914.

pivoted-at its middle part and having a spring-'19 connected with one of its ends.

There is a hand lever 20.shown as connected to one end of a bar 21, the other end of which. is pivoted. The intermediate part of trally pivoted crank arm, the other end 23 of 'which operates to start the body to dump.

4 rails, a pivotal body,

The connections to the chain are such that connecting the adjacent ends of said arms, a tail-board connected to the free ends of sziid first mentioned arms, and a link con i nected to the end of the other arm and to the body.
